Bom caminho. It will be getting safer after Valença do Minho.
From there you will go with the flow.
It will be the busiest part because lots of walkers will start to walk in Valença do Minho or Tuí for the last 100 kms or so to Santiago.
In Valença do Minho is an albergue. I myself prefer to stay in Valença do Minho rather than in the albergue in Tuí.
It is the last oportunity to stay in Portugal. Valença do Minho is worthwhile to visit, specially the famous fortification overlooking the Minho river, the famous Eiffel bridge and Tuí.
Keep in mind once crossing the bridge, the time is one hour ahead so if you start walking in Valença do Minho at f.ex. at 8h00 it is 9h00 in Spain..
Entering o Porriño keep an eye on (misleading) waymarkers.
The normal waymarkers lead you onto a bouring industrial estate for miles. There should be waymarkers to a green detour along a river but local entrepreneurs of restaurants frequently wipe them out and try to pass you their negociations.
In O Porriño is an albergue
Next day you follow to Redondela where in the middle of the town is a very busy, noisy and smelly municipal albergue.
Better is to walk 3 kms further to Cessantes where is the refúxio de La Jerézana, a rather new albergue, clean and comfortable with a very kind hospitalera, Marie who can serve you a nice diner and breakfast before the next day you will meet some steep ascendings and decendings to Pontevedra. The refúxio is waymarked by posters at trees and poles but easy to find
From Redondela you walk on rural paths
Once you arrive after about 3 kms from Redondela at a very busy N road to cross (at the corner of that crossing is a kind of bar /shop at your left) turn to the right and after about 100 meters you will find the refúxio at the right side just in a bend of the road.
Bom caminho
